Abstract

Data were collected from 642 orthopaedic interventions during which the images produced by X-rays were recorded. By examining these images, it is possible to determine the time that the orthopaedic surgeons’ hands were exposed to the direct radiation beam. The procedures with greater exposure to the direct beam were those involving the hand (median 15 s) and the wrist (median 13 s). Two surgeons wore a ring to measure the absorbed dose at the fingers: one on the dominant hand and the other on the non-dominant hand. The two surgeons performed 34 and 48 operations, respectively, in 14 months. The total doses measured with the rings were 2.30 and 1.04 mSv, respectively. The images of the interventions were examined, determining how much each individual hand was exposed. The interventional reference point (IRPeff (left or right)) was calculated by comparing the doses at the IRP with the exposure times of the right or the left hand. Summing the IRPeff of the two surgeons in 14 months, it is obtained the maximum values of 2.87 mGy for the left hand of one and 6.74 mGy for the right hand of the other, which are of the order of 1/100 of the annual dose limit for the extremities. © The Author(s) 2020.
